Reply To: dishwasher, hot or cold?

And I cannot imagine any manufacturer designing any component that would be damaged by hot water. It is a dishwasher, intended to be operated with hot water, followed by hot air circulated for drying. Heat transfer by thermal conductivity, radiation, and convection from normal dishwasher operation would certainly raise the temperature of any wetted component to at least that of the water from the hot water heater.
